Hillman 888 Axle Pushnut Fastener 7/16 in 12-Pack Alloy Steel Zinc

Description

Product Overview

The Hillman 888 Axle Pushnut Fastener is engineered to meet the demanding requirements of industrial and scientific environments where axle integrity is critical. Constructed from high‑grade alloy steel, each nut delivers exceptional tensile strength while the zinc coating adds corrosion resistance, extending service life even in harsh, moisture‑laden conditions. The 7/16″ tapered thread size, paired with a right‑hand thread orientation, ensures a secure, self‑locking fit that resists loosening under vibration. With a partially threaded design, the pushnut offers quick installation—simply align and press the nut onto the axle shaft without the need for additional tools or torque wrenches. The acorn head style provides a low‑profile finish that minimizes snagging and reduces the risk of accidental damage during handling or operation. Each package contains twelve uniformly sized nuts, each measuring 1.5 inches in length and weighing just 0.32 ounces, making them lightweight yet robust for a variety of mechanical assemblies.

Usage

Designed for versatility, the Hillman 888 pushnut excels in a range of applications, from automotive axle assemblies and agricultural equipment to heavy‑duty machinery and custom fabrication projects. Its tapered design allows it to accommodate slight variations in shaft diameter, providing a snug fit that distributes load evenly across the contact surface. This makes it ideal for securing drive shafts, gearboxes, and rotating components where precise alignment and torque retention are essential. The zinc‑plated finish not only protects against rust but also offers a smooth surface that reduces friction during installation, enabling faster assembly times on production lines. Whether you are a professional mechanic, a maintenance technician, or a DIY hobbyist, the pushnut’s straightforward press‑in method simplifies the fastening process, reducing labor costs and minimizing the chance of installation errors. The 12‑pack quantity ensures you have enough fasteners on hand for multiple projects or for maintaining a stocked inventory in a workshop or service facility.

FAQ

What size axle is compatible with the 7/16″ pushnut?

The 7/16″ tapered thread is designed for axles with a nominal diameter of 7/16 inches, typically ranging from 0.4375″ to 0.500″ due to the tapered profile, allowing a secure fit on slightly undersized or oversized shafts.

Can the pushnut be used on both steel and aluminum shafts?

Yes, the pushnut’s alloy steel construction and zinc coating make it suitable for fastening to both steel and aluminum shafts, provided the shaft material can accommodate the required thread engagement without stripping.

Is any special tool required for installation?

No special tools are needed. The pushnut is a press‑in type fastener; simply align the nut with the shaft and apply axial pressure until it seats fully. For larger assemblies, a light impact driver can be used to assist with insertion.

How does the zinc coating affect the nut’s performance in high‑temperature environments?

The zinc coating is rated for temperatures up to approximately 200°F (93°C). For applications exceeding this range, additional heat‑resistant coatings or stainless‑steel alternatives should be considered.

What warranty does Hillman provide for this product?

The Hillman 888 Axle Pushnut Fastener comes with a limited one‑year warranty covering material defects and workmanship, ensuring you receive a reliable product backed by the manufacturer’s support.
